2014-03-26drm/nouveau/bios: fix INDEX_ADDRESS_LATCHED trace printoutIlia Mirkin1-3/+2

2014-03-26drm/nouveau: use nv_debug for NV_DEBUG, make DRM a separate subflagIlia Mirkin2-4/+3
It's really confusing for NV_DEBUG's printing to be controlled via drm.debug while everything else is controlled via nouveau.debug. These messages can be turned on with nouveau.debug=DRM=debug. Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2014-03-26drm/nouveau: make hdmi device finding failure prints debug levelIlia Mirkin1-6/+5
The hdmi device is required for runtime pm. However it is not available on many esp older devices, which were all seeing these error messages. Take this opportunity to also convert to nv_debug instead of the DRM_* messages, like the rest of nouveau does.

2014-03-26drm/nve0/fifo: allocate usermem as neededAlexandre Courbot1-2/+2
Memory was always allocated for 4096 channels. Change this to allocate what we actually need according to the number of channels we use. Signed-off-by: Alexandre Courbot <[email protected]> Reviewed-by: Thierry Reding <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2014-03-26drm/nouveau: handle -EACCES runtime PM return codeAlexandre Courbot3-4/+4
pm_runtime_get*() may return -EACCES to indicate a device does not have runtime PM enabled. This is currently the case with platform devices on Nouveau, and is not an error in that context. Handle this case without failure. Signed-off-by: Alexandre Courbot <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2014-03-26drm/nouveau/abi16: fix handles past the 32nd oneIlia Mirkin1-2/+2
abi16->handles is a u64, so make sure to use 1ULL << val when modifying. Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2014-03-26drm/nouveau: replace ffsll with __ffs64Ilia Mirkin2-3/+3
The ffsll function is a lot slower than the __ffs64 built-in which compiles to a single instruction on 64-bit. It's also nice to avoid custom versions of standard functions. Note that __ffs == ffs - 1. Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2014-03-26drm/nouveau/hwmon: replace strict_strtol() with kstrtol()Jingoo Han1-2/+3
The usage of strict_strtol() is not preferred, because strict_strtol() is obsolete. Thus, kstrtol() should be used. Signed-off-by: Jingoo Han <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>

2014-03-25drm/radeon: set PIPE_CONFIG for 1D and linear tiling modes on CIKMarek Olšák2-4/+26
This fixes fast color clear with 1D-tiled single-sample surfaces and Hyper-Z corruption with 1D-tiled depth surfaces. Even though it seems it is not needed for 1D tiling, CMASK and HTILE are always 2D-tiled, thus the hw needs to know the actual pipe configuration for CMASK and HTILE addressing no matter what the tiling mode of the surface is.

2014-03-25drm/radeon: use the new drm helpers for dp auxAlex Deucher3-107/+104
Switch to the new dp helpers. The main difference is that the DP helpers don't allow an adjustable delay in the aux transaction, but I don't know that this is necessary. Signed-off-by: Alex Deucher <[email protected]> Acked-by: Christian König <[email protected]>
2014-03-25drm/dp: make aux retries less chattyAlex Deucher1-2/+2

2014-03-25drm/radeon/atom: rework encoder enable/disable sequenceAlex Deucher1-48/+34
This more closely matches what the vbios does and also adds a quirk for travis lvds displays and powers down the sink on DP displays which saves some power and may fix display issues in some cases. Signed-off-by: Alex Deucher <[email protected]> Acked-by: Christian König <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Highlights ---------- Re-factoring works over the exynos drm framework. - drm_crtc, drm_encoder/drm_connector are implemented by sub drivers directly. - Removing pm interfaces from each sub driver, and implementing them at top level of exynos drm. Add DisplayPort Transmitter driver. - Just moving existing driver from drivers/vides/exynos into drivers/gpu/drm/exynos. Add new LVDS bridge driver, PTN3460. - Placed in drivers/gpu/drm/bridge, and this device is used to transfer image signal from DP(DisplayPort) to LVDS Panel. So this driver will be used with DP driver moved into exynos drm. Add parallel panel support - With the re-factoring patch series, existing parallel panel support was broken by moving exynos_drm_display ops into each real connector driver, DP. So this patch series adds a new parallel panel module, exynos_drm_dpi, for supporting parallel panel, and also adds relevant bindings.

2014-03-24drm/gma500: add locking to fixed panel edid probingDaniel Vetter3-0/+11
With the recent addition of locking checks in commit 62ff94a5492175759546f8bc61383189d6b49122 Author: Daniel Vetter <[email protected]> AuthorDate: Thu Jan 23 22:18:47 2014 +0100 drm/crtc-helper: remove LOCKING from kerneldoc drm_add_edid_modes started to WARN about the mode_config.mutex not being held in the lvds and dp initialization code. Now since this is init code locking is fairly redudant if it wouldn't be for the drm core registering sysfs files a bit early. And the locking WARNINGs nicely enforce that indeed all access to the mode lists are properly protected. And a full audit shows that only i915 and gma500 touch the modes lists at init time. Hence I've opted to wrap up this entire mode detection sequence for fixed panels with the mode_config mutex for both lvds and edp outputs.

2014-03-24drm/exynos: restore parallel output interface supportAndrzej Hajda5-0/+360
The patch adds parallel output interface to FIMD device driver. It also restores support for panels initialized by boot loader, but without proper kernel driver. Driver uses video interface bindings to find connected panel. It uses drm_panel interface to interact with the panel.

In case fbdev is initialized before any output is connected, fb resolution defaults to 1024x768. After that any output with bigger resolution is ignored and fbdev is not displayed.

2014-03-24drm/exynos: Remove the exynos_drm_connector shimSean Paul4-29/+6

2014-03-24drm/exynos: Add create_connector callbackSean Paul2-0/+5
This creates a new display hook called create_connector. The purpose is to allow the display driver to create its own drm_connector instead of using the exynos_drm_connector.

2014-03-24drm/exynos: Consolidate suspend/resume in drm_drvSean Paul5-288/+170
This patch removes all of the suspend/resume logic from the individual drivers and consolidates it in drm_drv. This consolidation reduces the number of functions which enable/disable the hardware to just one -- the dpms callback. This ensures that we always power up/down in a consistent manner.

2014-03-24drm/exynos: Clean up FIMD power on/off routinesSean Paul1-111/+134
This patch separates the fimd_activate function into poweron/poweroff functions to be more consistent with the other drivers in exynos drm. It also properly cleans up after failures in poweron. The functions have also been shuffled around such that they are all in the same spot in the file and poweron/poweroff can be called from the dpms function.
